Hey guys,
I'm building a 1500w 12v bench supply using 2 750w PSUs (yes, I know I won't get the full 1500w, but let's just ignore that for now). I'll be using it for 12v audio output testing (car audio testing)
I know both supplies will be case grounded to the chassis... But would it be better to open the supplies up, and actually physically connect the green AC ground together, then to the main chassis, rather than relying on screws, case grounding, multiple grounds etc.
Will I have any issues if I connect all the AC grounds together, and ground directly to the chassis its self, or should I leave the grounds attached to their respective PSUs and just go about it that way.
The reason I ask, is both supplies AND the chassis is powdercoated, and I don't really want to have two separate floating grounds. Although, to be fair, two separate floating grounds may be smarter since this is for audio. Basically, what would you do?
Cheers,
